Platinum was an ore added in the 01/17/2017 update, the last update excluding events. It has a dark grey/black appearance and doesn't glow at all, making it difficult to spot. It spawns between 400m and 1000m of depth with an uncommon chance of spawn.
Platinum Pickaxe Edit
The Platinum Pickaxe can be unlocked when reaching Mining Operations Level 9. The Platinum Pickaxe has a power of 3, a range of 7.5, and a delay of 0.15. Despite this Pickaxe having a relatively low Pickaxe power it is able to by pass ore level requirements. This Pickaxe will really only be used for it's special property of bypassing ore level requirements, and by the time the player receives it, Mithril may well be the only locked ore. Other than that the amount of players using this pick will be scarce due to the such high level it is unlocked for only a minor use, by the time a player unlocks this they will most likely have a pickaxe overpowering this one by far, such as Moonstone.
